Disclosure of Invention
In the temperature and humidity control, particularly the humidity control, performed by such a conventional air conditioner, air conditioning is performed by an air conditioning room, and it is difficult to apply the air conditioning to a system for blowing air to a plurality of living rooms by a conveyance fan. That is, in the conventional air conditioner, the ambient humidity is detected, and the control target humidity is set and maintained for the ambient humidity, thereby providing an environment in which the humidity is comfortable. Here, the humidity of the room in which the air conditioner is installed is controlled by the air conditioner, and is hardly affected by the outside.
In contrast, in the above system, air of various humidities flows into the air-conditioning room every time when the system is connected to a plurality of living rooms, and therefore, the humidity environment of the air-conditioning room greatly changes in a short time. Therefore, in order to control the humidity of the air-conditioning room in such a situation within a predetermined range, it is necessary to provide a very large air-conditioning room having a sufficient margin for a plurality of living rooms to control the humidity, or to sufficiently improve the dehumidification capability and the humidification capability. However, this method is inefficient in terms of space or energy, and a new humidity control method is required.

In the drawings, substantially the same components are denoted by the same reference numerals, and redundant description is omitted or simplified.
(embodiment mode 1)
First, an air conditioning system 20 according to embodiment 1 of the present invention will be described with reference to fig. 1. Fig. 1 is a schematic connection diagram of an air conditioning system 20 according to embodiment 1.
The air conditioning system 20 includes an outside air introducing fan 4, a plurality of exhaust fans 5 ( exhaust fans 5a, 5b, 5c, 5d), a plurality of conveyance fans 3 ( conveyance fans 3a, 3b, 3c, 3d), a plurality of circulation fans 6(6a, 6b, 6c, 6d), a room temperature sensor 11 ( room temperature sensors 11a, 11b, 11c, 11d), a room humidity sensor 12 ( room humidity sensors 12a, 12b, 12c, 12d), an air conditioning room temperature sensor 14, an air conditioning room humidity sensor 15, an air conditioner 9, a humidifier 16, a dehumidifier 17, an input/output terminal 19, and a system controller 10 (corresponding to an air conditioning system controller).
Air conditioning system 20 is installed in general house 1, which is one example of a building. In addition to a plurality of (four in the present embodiment) living rooms 2 ( living rooms 2a, 2b, 2c, and 2d), the general home 1 further includes at least one air-conditioning room 18 independent of the living room 2. Here, the general house 1 (house) is a house provided as a place where a resident lives privately, and the room 2 includes a living room, a dining room, a bedroom, a cubicle, a child room, and the like as a general structure. In addition, the living room provided by the air conditioning system 20 may include a toilet, a bathroom, a washroom, a changing room, and the like.
In the air-conditioned room 18, the air sent from each living room 2 is mixed with each other. The outside air is taken into the air-conditioned room 18 by the outside air introducing fan 4, and is mixed with the air sent from each living room 2 by the circulating fan 6. The air in the air-conditioning room 18 is conditioned by controlling the temperature and humidity thereof by the air conditioner 9, the humidifier 16, and the dehumidifier 17 provided in the air-conditioning room 18, and air to be delivered to the living room 2 is generated. The air conditioned by the air-conditioning room 18 is delivered to each living room 2 by the delivery fan 3. Here, the air-conditioning room 18 is a space including a certain size in which the air conditioner 9, the other humidifiers 16, the dehumidifier 17, and the like can be disposed, and air conditioning of each living room can be controlled, but is not a living space and does not basically mean a room where a resident stays.
The air in each room 2 is sent to the air-conditioning room 18 by the circulation fan 6, and is discharged as outside air from the inside of the room 2 to the outside of the general house 1 by the exhaust fan 5. The air conditioning system 20 performs ventilation of the 1 st ventilation system by controlling the exhaust air volume of the exhaust fan 5 to discharge outside air from the room, and controlling the supply air volume of the outside air introduction fan 4 to take outside air into the room while interlocking with the exhaust air volume of the exhaust fan 5.
The outside air introducing fan 4 is a fan that takes outside air into the room of the general house 1, and is suitable for the air supply function of an air supply fan or a heat exchange ventilator. As described above, the outside air taken in by the outside air introducing fan 4 is introduced into the air-conditioned room 18. The supply air volume of the outside air introduction fan 4 is configured to be settable in a plurality of stages, and is set in accordance with the exhaust air volume of the exhaust fan 5 as described later.
The exhaust fan 5 is a fan that exhausts a part of the air in the corresponding room 2 as outside air through an exhaust duct, for example, and is suitable for the exhaust function of a ceiling fan, a wall-mounted fan, a range hood, a heat exchange fan, and the like. In fig. 1, the exhaust duct connected to the exhaust fan 5 is directly connected to the outside of the general house 1, but when the exhaust function of the heat exchange ventilator is used, the exhaust duct is temporarily connected to the heat exchange ventilator and then connected to the outside of the general house 1. That is, the air passing through the exhaust duct and the air passing through the air supply duct of the heat exchange ventilator exchange heat with each other, and thereafter, the air is discharged to the outside of the general house 1. Exhaust fan 5a is installed in room 2a, exhaust fan 5b is installed in room 2b, exhaust fan 5c is installed in room 2c, and exhaust fan 5d is installed in room 2 d.
Each exhaust fan 5 is configured to have an exhaust air volume that can be set in a plurality of stages. In a normal state, each exhaust fan 5 is controlled to achieve a preset exhaust air volume. Then, the exhaust air volume is controlled for each of the exhaust fans 5a to 5d in accordance with the setting of the user or the values acquired by various sensors.
The conveyance fans 3a to 3d are provided on, for example, the wall surface of the air-conditioning room 18 in correspondence with the rooms 2a to 2 d. The air in the air-conditioning room 18 is delivered to the room 2a by the delivery fan 3a via the delivery duct, delivered to the room 2b by the delivery fan 3b via the delivery duct, delivered to the room 2c by the delivery fan 3c via the delivery duct, and delivered to the room 2d by the delivery fan 3d via the delivery duct. Further, the transport ducts connected to the rooms are provided independently.
Circulation fan 6a is installed in room 2a, circulation fan 6b is installed in room 2b, circulation fan 6c is installed in room 2c, and circulation fan 6d is installed in room 2 d. A part of the air in each of rooms 2a to 2d is sent to air-conditioning room 18 through the circulation duct by corresponding circulation fans 6a to 6 d. The circulation duct connecting the air-conditioning room 18 and each living room may be provided independently, but a plurality of branch ducts which are part of the circulation duct may be joined together in the middle to form one circulation duct, which is then connected to the air-conditioning room 18.
The air conditioner 9 corresponds to an air conditioner, and controls air conditioning in an air conditioning room 18. The air conditioner 9 cools or heats the air in the air-conditioned room 18 so that the temperature of the air in the air-conditioned room 18 becomes a set target temperature (air-conditioned room target temperature).
The humidifier 16 humidifies the air in the air-conditioning room 18 so that the humidity of the air in the air-conditioning room 18 becomes the air-conditioning room target humidity when the humidity is lower than a set target humidity (air-conditioning room target humidity). The humidifier 16 may be incorporated in the air conditioner 9, but in order to obtain humidification capacity corresponding to a plurality of living rooms 2, the air conditioner 9 preferably includes a separate humidifier 16. Here, the air-conditioning room target humidity is defined as a predetermined humidity range defined by a lower limit as a minimum humidity and an upper limit as a maximum humidity. In addition, the minimum humidity, the maximum humidity, and the humidity processed in the present embodiment are expressed as relative humidity, respectively, and can be processed as absolute humidity by a prescribed conversion process. In this case, it is preferable that the entire process in the air conditioning system including the humidity of the living room be treated as the absolute humidity.
The dehumidifier 17 dehumidifies the air in the air-conditioning chamber 18 so that the humidity of the air in the air-conditioning chamber 18 becomes the air-conditioning chamber target humidity when the humidity is higher than a set target humidity (air-conditioning chamber target humidity). Further, although the dehumidifier 17 may be built in the air conditioner 9, the air conditioner 9 preferably includes a separate dehumidifier 17 in order to obtain dehumidification capability corresponding to a plurality of rooms 2.
Room temperature sensor 11a is installed in room 2a, room temperature sensor 11b is installed in room 2b, room temperature sensor 11c is installed in room 2c, and room temperature sensor 11d is installed in room 2 d. The room temperature sensors 11a to 11d are sensors that acquire the indoor temperatures of the corresponding rooms 2a to 2d and transmit the temperatures to the system controller 10.
Room humidity sensor 12a is installed in room 2a, room humidity sensor 12b is installed in room 2b, room humidity sensor 12c is installed in room 2c, and room humidity sensor 12d is installed in room 2 d. The room humidity sensor 12 is a sensor that acquires the indoor humidity (room humidity) of each of the corresponding rooms 2a to 2d and transmits the humidity to the system controller 10.
The air-conditioning room temperature sensor 14 is a sensor that acquires the temperature of the air-conditioning room 18 and sends it to the system controller 10. Further, the air-conditioning room temperature sensor 14 may be built in the air conditioner 9, but when built in the air conditioner 9, only information on the periphery of the air conditioner 9 (for example, the vicinity of the air supply port) can be obtained. As described above, since the outside air is mixed with the air sent from each living room 2, it is desirable to include the air-conditioning room 18 separately from the air conditioner 9 in order to obtain information as the whole air-conditioning room 18.
The air-conditioning room humidity sensor 15 is a sensor that acquires the humidity of the air in the air-conditioning room 18, that is, the air-conditioning room humidity, and sends it to the system controller 10. For the same reason as the air-conditioning room temperature sensor 14, it is also preferable that the air-conditioning room humidity sensor 15 be provided separately from the air conditioner 9 in order to obtain information on the entire air-conditioning room 18.
The system controller 10 is a controller that controls the entire air conditioning system 20. The system controller 10 is communicably connected with the outside air introducing fan 4, the exhaust fan 5, the conveying fan 3, the circulating fan 6, the room temperature sensor 11, the room humidity sensor 12, the air-conditioning room temperature sensor 14, the air-conditioning room humidity sensor 15, the air conditioner 9, the humidifier 16, and the dehumidifier 17 by wireless communication.
The system controller 10 sets the supply air volume of the outside air introduction fan 4 and controls the outside air introduction fan 4 and the exhaust fan 5 in conjunction with each other so as to achieve an air volume corresponding to the exhaust air volume of the exhaust fan 5. Thereby, ventilation by the 1 st ventilation method is performed for the general house 1.
The system controller 10 controls the air conditioner 9, the humidifier 16, and the dehumidifier 17 as an air conditioner so that the temperature and/or the humidity of the air-conditioning room 18 becomes the air-conditioning room target temperature and/or the air-conditioning room target humidity set in the air-conditioning room 18, based on the temperature and the humidity of the air-conditioning room 18 acquired by the air-conditioning room temperature sensor 14 and the air-conditioning room humidity sensor 15.
The system controller 10 sets the airflow rate of the conveyance fan 3 or the airflow rate of the circulation fan 6 based on the indoor temperature and/or the indoor humidity of each room 2 acquired by the room temperature sensor 11 and the room humidity sensor 12, the target temperature (room target temperature) and/or the target humidity (room target humidity) set for each of the rooms 2a to 2d, and the like.
Thus, the air conditioned by the air-conditioning room 18 is delivered to each living room 2 in accordance with the air volume set in each of the delivery fans 3, and the air in each living room 2 is delivered to the air-conditioning room 18 in accordance with the air volume set in each of the circulation fans 6. Therefore, the indoor temperature and/or the indoor humidity of each living room 2 are controlled to the target living room temperature and/or the target living room humidity.
Here, the system controller 10 and the outside air introducing fan 4, the exhaust fan 5, the conveying fan 3, the circulating fan 6, the room temperature sensor 11, the room humidity sensor 12, the air-conditioning room temperature sensor 14, the air-conditioning room humidity sensor 15, the air conditioner 9, the humidifier 16, and the dehumidifier 17 are connected by wireless communication, and thus a complicated wiring process can be eliminated. However, the whole of them may be configured to be communicable by wired communication, or the system controller 10 and a part of them may be configured to be communicable by wired communication.
The input/output terminal 19 is communicably connected to the system controller 10 by wireless communication, receives input of information necessary for constructing the air conditioning system 20, stores the input in the system controller 10, and acquires and displays the state of the air conditioning system 20 from the system controller 10. Examples of the input/output terminal 19 include a mobile information terminal such as a mobile phone, a smart phone, and a tablet.
The input/output terminal 19 is not necessarily connected to the system controller 10 by wireless communication, and may be communicably connected to the system controller 10 by wired communication. In this case, the input/output terminal 19 may be implemented by, for example, a wall-mounted remote controller.
Next, each function of the system controller 10 will be described with reference to fig. 2. Fig. 2 is a schematic functional block diagram of the system controller 10.
The system controller 10 includes a living room target humidity acquisition unit 54, an air-conditioning room humidity control unit 55, an air-blowing amount determination unit 40, a fan air-blowing amount control unit 31, and a storage unit 46.
The living room target humidity acquiring unit 54 acquires the living room target humidity set together with the entire living room 2 through the input/output terminal 19. The target living room humidity is set as a predetermined humidity range defined by a lower limit as a minimum humidity and an upper limit as a maximum humidity. In the present embodiment, the living room target humidity and the air-conditioning room target humidity are the same. In the present embodiment, the user can set the target indoor humidity, or can set it as a fixed value in the air conditioning system. The maximum humidity and the minimum humidity acquired or set in advance by the living room target humidity acquiring unit 54 are stored in the storage unit 46.
The air-conditioning-room humidity control unit 55 controls the humidity in the air-conditioning room to the air-conditioning-room target humidity acquired by the living-room target humidity acquiring unit 54 by using the humidifier 16 and the dehumidifier 17. Specifically, when the humidity of the air-conditioning room acquired by the air-conditioning room humidity sensor 15 is higher than the maximum humidity constituting a predetermined humidity range, the dehumidifier 17 is operated. When the humidity of the air-conditioning room acquired by the air-conditioning room humidity sensor 15 is lower than the minimum humidity, the humidifier 16 is operated.
The air-blowing amount determination unit 40 includes a humidity determination unit 53, a humidity difference comparison unit 56, and a height determination unit 57. The air-blowing-amount determining unit 40 determines the air-blowing amount of the conveyance fan 3 based on the indoor humidity of each room obtained by the room humidity sensor 12 and the humidity of the air-conditioning room 18 obtained by the air-conditioning room humidity sensor 15. The flow of determining the air blowing amount will be described later.
The humidity determination unit 53 determines whether or not the indoor humidity of each room 2 is within the predetermined humidity range based on the indoor humidity of each room 2 acquired by the room humidity sensor 12 and the air-conditioning room target humidity indicating the predetermined humidity range, which is the room target humidity acquired by the room target humidity acquisition unit 54.
The humidity difference comparison unit 56 calculates the difference between the indoor humidity of each room acquired by the room humidity sensor 12 and the humidity of the air-conditioning room 18 acquired by the air-conditioning room humidity sensor 15. Specifically, for example, when the humidity in room 2a is 90% and the humidity in the air-conditioning room is 50%, the difference is 40. In addition, in calculating the difference, it is not always necessary to obtain the difference between the humidity expressed in% and, for example, the difference, that is, the magnitude of the difference between the humidity of the air-conditioning room and the humidity of the living room may be calculated from the moisture amount obtained based on the humidity, or the like.
The height determination unit 57 determines the height of the indoor humidity of each room acquired by the room humidity sensor 12 with respect to the humidity of the air-conditioning room 18 acquired by the air-conditioning room humidity sensor 15. Specifically, for example, when the humidity of room 2a is 90% and the air-conditioning room humidity is 50%, it is determined that the humidity of room 2a is "higher than" 50% of the air-conditioning room humidity. On the other hand, when the humidity of room 2c is 30% and the air-conditioning room humidity is 50%, it is determined that the humidity of room 2c is "lower than" 50% of the air-conditioning room humidity. These determinations may be made for all rooms, or may be made only for rooms with a humidity higher than the highest humidity and only for rooms with a humidity lower than the lowest humidity.
The fan airflow control unit 31 controls the airflow of each of the plurality of conveyance fans 3a to 3d provided in association with each of the plurality of rooms 2a to 2d to the airflow of each of the conveyance fans 3a to 3d determined by the airflow determination unit 40. The fan airflow control unit 31 can control the circulation fans 6a to 6d, and a detailed description thereof will be omitted.
The storage unit 46 is a so-called memory that stores the maximum humidity and the minimum humidity, which are predetermined humidity ranges acquired or set in advance by the living room target humidity acquisition unit 54. In addition, the storage unit 46 is also used when it is necessary to store information such as numerical values for the control of another system controller 10.
Next, an air conditioning process performed by the system controller 10 will be described with reference to fig. 3 to 8C. Fig. 3 is a flowchart showing the air conditioning process. Fig. 4 is a flowchart showing the humidity control process of the air-conditioning room. Fig. 5 is a flowchart showing the fan airflow setting process. Fig. 6 is a flowchart showing the air blowing amount determination process. Fig. 7A and 7B are diagrams showing an example of the relationship between the air-conditioning room target humidity, the air-conditioning room humidity, and the room humidity. Fig. 8A, 8B, and 8C are diagrams showing another example of the relationship between the air-conditioning room target humidity, the air-conditioning room humidity, and the room humidity.
As shown in fig. 3, the air conditioning process executed by the system controller 10 is mainly composed of an air conditioning room humidity control process S100 and a fan airflow rate setting process S200, and is executed in the following order.
When the user executes the air conditioning process, first, the system controller 10 executes the air conditioning room humidity control process S100 shown in fig. 4.
In the air-conditioning room humidity control process S100, the system controller 10 acquires the room target humidity set by the input/output terminal 19 and stores the room target humidity in the storage unit 46 (S101). Here, the room target humidity is a humidity that the user feels comfortable, and is a humidity common to all rooms. The living room target humidity is defined as a predetermined humidity range defined with a lower limit as a minimum humidity and an upper limit as a maximum humidity. The predetermined humidity range is a target humidity range of the air-conditioned room 18, i.e., is the same as the air-conditioned room target humidity. The user sets the maximum humidity to 65% and the minimum humidity to 45% for example, with respect to the input/output terminal 19, and the system controller 10 acquires the room target humidity input to the input/output terminal 19 as the air-conditioning room target humidity via the room target humidity acquiring unit 54.
If the air-conditioning chamber target humidity is acquired, the air-conditioning chamber humidity control part 55 maintains the humidity of the air-conditioning chamber 18 within the air-conditioning chamber target humidity range using the air-conditioning chamber humidity sensor 15, the humidifier 16, and the dehumidifier 17 (S102).
The target humidity of the air-conditioning room is maintained as follows. That is, when the air-conditioning room humidity acquired by the air-conditioning room humidity sensor 15 is higher than the maximum humidity, the dehumidifier 17 is operated. When the air-conditioning room humidity acquired by the air-conditioning room humidity sensor 15 is lower than the minimum humidity, the humidifier 16 is operated. If the variation in the humidity of the air-conditioning room caused by the air flowing into the air-conditioning room 18 after the air-conditioning room humidity control process is taken into consideration, dehumidification is performed on the premise of a predetermined humidity range, for example, to a humidity lower than the maximum humidity within a certain range (for example, -5%) at the time of dehumidification. Further, the humidification may be performed to a humidity higher than the minimum humidity within a certain range (for example, + 5%).
Through the above processing, the humidity of the air-conditioning chamber 18 is maintained within a predetermined humidity range.
Next, the system controller 10 executes a fan airflow setting process S200 shown in fig. 5.
In the fan airflow setting process S200, the airflow determination unit 40 acquires the air-conditioning room humidity via the air-conditioning room humidity sensor 15 (S201). Further, the air flow amount determination unit 40 acquires the room humidity of each room 2 via the room humidity sensor 12 (S202). Then, the system controller 10 acquires the maximum humidity and the minimum humidity, which are predetermined humidity ranges, from the storage unit 46 via the living room target humidity acquisition unit 54 (S203).
Next, the air-blowing amount determination unit 40 determines whether or not the room humidity in each room is within a predetermined humidity range by the humidity determination unit 53 (S203).
Here, the process ends as long as all rooms are within a predetermined humidity range (S204 Yes → end).
If at least one room is not in the predetermined humidity range, the humidity difference comparison unit 56 calculates the difference between the room humidity and the air-conditioning room humidity in the room (room not in the humidity range) corresponding to the room (S204 No → S205). Then, the height determination unit 57 determines whether the room humidity in the room is higher or lower than the humidity of the air-conditioning room, that is, the height of the room humidity with respect to the humidity of the air-conditioning room (S206). Here, the determination of the level may be made by comparing the air-conditioning room humidity and the room humidity acquired by the air-conditioning room humidity sensor 15 as the humidity of the air-conditioning room, and the same result is obtained even if the level is determined to be higher than a predetermined humidity range. The high/low determination unit 57 determines the high/low, and classifies the rooms 2 (rooms 2a to 2d) that are not within the predetermined range into high-humidity rooms higher than the maximum humidity and low-humidity rooms lower than the minimum humidity, and correlates the temperature difference with the temperature difference compared by the humidity difference comparison unit 56. That is, in this process, the air flow amount determination unit 40 can grasp the number of high-humidity rooms and low-humidity rooms and the difference between the humidity and the humidity of each air-conditioning room.
If the above processing is completed, the air-blowing amount determination unit 40 performs air-blowing amount determination processing (S300).
The air-blowing amount determination unit 40 executes air-blowing amount determination processing S300 shown in fig. 6. That is, in the air flow determination process S300, first, the air flow determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room.
Here, when there are only a plurality of low-humidity rooms, the amount of air blown into the room with a large humidity difference is determined to be large (S301 Yes → S303). This process is explained in detail with reference to fig. 7A. Fig. 7A shows an example in which only a plurality of low-humidity rooms are present. In fig. 7A, a denotes a room 2a, b denotes a room 2b, c denotes a room 2c, d denotes a room 2d, and the numerical value at the bottom denotes room humidity. The maximum humidity was 65%, the minimum humidity was 45%, and the air-conditioning room humidity was 50%.
According to fig. 7A, only 2 rooms (room 2c and room 2d) exist in the low-humidity room. The humidity difference (absolute value) between room 2c and the air-conditioned room is 20%, and the humidity difference between room 2d and the air-conditioned room is 30%. In this case, the air-blowing amount determination unit 40 sets the air-blowing amount of the conveyance fan 3d corresponding to the room 2d having a large humidity difference to be larger than the air-blowing amount of the conveyance fan 3c corresponding to the room 2 c. Here, the air blowing amount can be set to the air blowing capacity or the operation gap of the conveyance fan. For example, if the air blowing amount of the conveyance fan 3 can be set to 10 stages, i.e., the air blowing amount 1 to the air blowing amount 10, in order from the small air blowing amount, the air blowing amount determination unit 40 determines the air blowing amount of the conveyance fan 3d as the maximum air blowing amount 10. The air-blowing amount determination unit 40 determines the air-blowing amount of the conveyance fan 3c to be smaller than the air-blowing amount 7 of the conveyance fan 3d, for example.
As a result, the air in the air-conditioning room flows into rooms 2c and 2d, and the room humidity in each room gradually approaches the predetermined humidity range. At this time, the humidity of room 2d having a large humidity difference from the humidity of the air-conditioned room, which is slightly uncomfortable due to the difference in the air blowing amount, is improved at a higher speed than the humidity of room 2c having a smaller humidity difference from the humidity of the air-conditioned room than room 2 d. That is, the air blowing amount determination unit 40 preferentially improves the humidity of the room in a room with a low humidity environment.
At this time, since the air-conditioning room humidity gradually decreases from 50% due to the inflow of the dry air in rooms 2c and 2d, when the humidity is lower than the minimum humidity, air-conditioning room humidity control unit 55 operates humidifier 16 as necessary to maintain the air-conditioning room humidity within a predetermined humidity range.
The air-blowing amount determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and similarly determines the air-blowing amount of a room having a large humidity difference to be large even when there are a plurality of high-humidity rooms (S301 No → S302 Yes → S303).
This process is explained in detail with reference to fig. 7B. Fig. 7B shows an example in which only a plurality of high-humidity rooms are present.
According to fig. 7B, only 2 rooms (room 2a and room 2B) are present in the high-humidity room. The humidity difference (absolute value) between room 2a and the air-conditioned room is 40%, and the humidity difference between room 2b and the air-conditioned room is 30%. In this case, air-blowing amount determination unit 40 sets the air-blowing amount of conveyance fan 3a corresponding to room 2a having a large humidity difference to be larger than the air-blowing amount of conveyance fan 3b corresponding to room 2 b. That is, here, the air-blowing amount determination unit 40 determines the air-blowing amount 10 in which the air-blowing amount of the conveyance fan 3a is the maximum value. The air-blowing amount determination unit 40 determines the air-blowing amount of the conveyance fan 3b to be smaller than the air-blowing amount 7 of the conveyance fan 3b, for example.
As a result, the air in the air-conditioning room flows into rooms 2a and 2b, and the room humidity in each room gradually approaches the predetermined humidity range. At this time, the humidity of room 2a having a large humidity difference from the humidity of the air-conditioned room, which is slightly uncomfortable due to the difference in the amount of blown air, is improved at a higher rate than the humidity of room 2b having a smaller humidity difference from the humidity of the air-conditioned room than room 2 a. That is, the air blowing amount determination unit 40 preferentially improves the humidity of the room in a room with a low humidity environment.
At this time, since the air-conditioning room humidity gradually increases from 50% due to the inflow of the humid air in the rooms 2a and 2b, the air-conditioning room humidity control unit 55 operates the dehumidifier 17 to maintain the air-conditioning room humidity within a predetermined humidity range as necessary when the humidity is higher than the maximum humidity.
The air-blowing amount determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and sets the air-blowing amount of the room with a small humidity difference to be large when both the high-humidity room and the low-humidity room are present (S302 No → S304 Yes → S305).
This process will be described in detail with reference to fig. 8A, 8B, and 8C. Fig. 8A shows an example in which only a plurality of low-humidity rooms are present. Note that fig. 8A shows the same behavior as fig. 7A and 7B.
Referring to fig. 8A, room 2c, which is a low-humidity room, and room 2a, which is a high-humidity room, are present. The humidity difference between room 2c and the air-conditioned room is 20%, and the humidity difference between room 2a and the air-conditioned room is 40%. In this case, the air-blowing amount determination unit 40 sets the air-blowing amount of the conveyance fan 3a corresponding to the room 2a having the large humidity difference to be smaller than the air-blowing amount of the conveyance fan 3c corresponding to the room 2c having the small humidity difference. In other words, the air-blowing amount determination unit 40 sets the air-blowing amount of the conveyance fan 3c corresponding to the room 2c having a small humidity difference to be larger than the air-blowing amount of the conveyance fan 3a corresponding to the room 2a having a large humidity difference. Specifically, here, the air-blowing-amount determining unit 40 determines the air-blowing amount 10 at which the air-blowing amount of the conveyance fan 3c is the maximum value. The air-blowing amount determination unit 40 determines the air-blowing amount of the conveyance fan 3a to be smaller than the air-blowing amount of the conveyance fan 3c, for example, the air-blowing amount 5.
As a result, the air in the air-conditioning room flows into rooms 2a and 2c, and the room humidity in each room gradually approaches the predetermined humidity range. At this time, as shown in fig. 8B, the humidity of room 2c having a small humidity difference is first improved by the difference in the amount of air blown.
Here, the difference from S303 is that the variation in humidity in the air-conditioning room is suppressed to the minimum by controlling the inflow amount of air from two living rooms. That is, the inflow amount of air from a low-humidity room having a small humidity difference to the air-conditioning room is set to be much larger than the inflow amount of air from a high-humidity room having a large humidity difference to the air-conditioning room, whereby the inflow and outflow of moisture to and from the air-conditioning room are controlled to be (ideally) equivalent. This can suppress the fluctuation of the humidity of the air-conditioning room, and therefore, the operation of the humidifier 16 or the dehumidifier 17 can be suppressed, and energy saving control can be realized. In addition, the air-conditioning chamber can be operated efficiently in terms of humidity, and the air-conditioning chamber can be miniaturized.
The air flow amount determination unit 40 may set the air flow amount of the conveyance fan 3c corresponding to the room 2c having a small humidity difference to the air flow amount of the conveyance fan 3a corresponding to the room 2a having a large humidity difference. Specifically, the air-blowing amount determination unit 40 determines the air-blowing amount of the conveyance fan 3c and the air-blowing amount of the conveyance fan 3a to be, for example, the air-blowing amount 10. In this case, as shown in fig. 8C, first, the humidity of room 2C is improved. In this case, while the humidity of room 2c is improved, the low-humidity air in room 2c and the high-humidity air in room 2a cancel out the humidity, so that the fluctuation in the humidity of the air-conditioning room can be suppressed. In addition, since the humidity of the living room 2a is high, the humidity of the air-conditioning room is expected to rise slightly, and the air-conditioning room humidity control unit 55 may be adapted to the dehumidifier 17 as necessary. Even for this process, it can contribute to energy saving control and downsizing of the air conditioner.
The air flow amount determination unit 40 counts the number of low-humidity rooms and the number of high-humidity rooms with respect to the humidity of the air-conditioning room, and indicates that one low-humidity room or one high-humidity room is present when both high-humidity rooms and low-humidity rooms are not present. In this case, the air-blowing-amount determining unit 40 can transit the humidity of the room to a predetermined humidity range by blowing air to the low-humidity room or the high-humidity room corresponding thereto in accordance with a predetermined air amount (S304 No → S306).
Although the air conditioning process has been described above, the air conditioning process is repeated independently of the air-conditioning-room humidity control process S100 and the fan airflow rate setting process S200 after the air conditioning process is initially executed.
The air conditioning system and the system controller according to the present invention have been described above, but the above embodiments are merely examples and are not limited thereto.
For example, the circulation fans 6a to 6d and the conveyance fans 3a to 3d communicate with each other through a duct connecting the living room and the air-conditioned room. However, the circulation fans 6a to 6d do not necessarily have to be connected by a duct, and a space such as a corridor connecting rooms can be regarded as a duct. In this case, the air in the living room is sent from the living room to the corridor by the circulation fans 6a to 6 d. The air delivered into the living room of the corridor is taken into the air-conditioning room 18 communicating with the corridor. The air-conditioned room 18 may be taken in by newly providing a circulation fan on a wall surface of the air-conditioned room 18 facing the corridor, or by making the air-conditioned room negative in pressure without using a circulation fan. Even with this configuration, the cycle efficiency is expected to be reduced compared to the case of connection by a pipe, and it is possible to contribute to the air conditioning system.
Next, an air conditioning room 18 according to embodiment 1 of the present invention will be described with reference to fig. 9, 10, and 11. Fig. 9 and 10 are schematic views of the air-conditioning room 18 according to embodiment 1, fig. 9 is a schematic view of the air-conditioning room in a case where the air-conditioning room is divided into three sections, and fig. 10 is a schematic view of the air-conditioning room in a case where the air-conditioning room is divided into two sections. Fig. 11 is a schematic functional block diagram of the system controller in the case where the air-conditioning room is divided into three zones. In fig. 11, a first space humidity calculating unit 58 is added to the schematic functional block diagram shown in fig. 2.
In fig. 1, the air-conditioning room 18 is not partitioned, i.e., is located in the same space, and the temperature and humidity thereof are controlled by the air conditioner 9, the humidifier 16, and the dehumidifier 17. In contrast, in fig. 9 and 10, by partitioning the air-conditioning room 18, efficient dehumidification/humidification can be achieved.
Specifically, as shown in fig. 9, dehumidification, temperature control, and humidification are performed in different spaces. For example, as shown in fig. 9, the air-conditioning room 18 is divided into three independent spaces, i.e., a first space 22, a second space 23, and a third space 24, by a partition plate 21. In this case, the air conditioner 9, the humidifier 16, the dehumidifier 17, and the like are also controlled by the system controller 10 in the same manner as described above. The first space 22, the second space 23, and the third space 24 are arranged in this order from the upstream to the downstream, and the air in each space is blown downstream by the conveyance fan 3.
The partition plate 21 is a plate formed of a wooden plate, a gypsum plate, or the like, having a function of partitioning the first space 22 and the second space 23, and a function of partitioning the second space 23 and the third space 24. In addition to the used plates, the partition plate 21 can further prevent heat or humidity from moving between the spaces by bonding the heat insulating plates. Partition plate 21 has a space connecting opening 25 of a circular hole or a rectangular hole in a part of the plate surface. Thereby, the first space 22 and the second space 23 and the third space 24 become independent spaces mutually ventable via the space connecting opening 25.
In the case where partition plate 21 is not present, space connecting opening 25 has an opening area of, for example, 30% or less, more preferably 20% or less, with respect to the area of the surface where first space 22 and second space 23 meet. This is because, when the space connecting opening 25 is too large, the degree of contribution to the efficiency of dehumidification/humidification performance decreases, and when it is too small, the pressure loss increases, and the ventilation efficiency between the spaces may be adversely affected. In addition, although the space connecting opening 25 is provided as a simple opening, the efficiency of air blowing from the upstream independent space to the downstream independent space can be improved by providing a fan, such as a pipe fan, for forcibly blowing air in the opening.
The first space 22 is provided upstream with a first air supply opening 26 for supplying indoor air and a second air supply opening 27 for supplying outdoor air, and downstream with a space connection opening 25 to the second space 23. The first space 22 is provided with a dehumidifier 17, a first space temperature sensor 28, and a first space humidity sensor 29. With this configuration, the indoor air from the first air supply opening 26 and the outdoor air from the second air supply opening 27 are mixed in the first space 22. The mixed air typically contains more fresh air outside than inside the room. Since the air sent from the sending fans 3a to 3d is returned to the first space 22 via the rooms 2a to 2d, the indoor air is at the target temperature, the temperature close to the target humidity, and the humidity set in the system controller 10. On the other hand, in a high-temperature and high-humidity environment in summer or at the time of heavy rain, for example, outdoor air is at a high temperature and high humidity with respect to the set target temperature and target humidity. As described above, since more outdoor air is supplied to the first space 22 than indoor air, the first space 22 becomes a high-temperature and high-humidity environment. When the air in the mixed first space 22 is higher than the air-conditioning-chamber target humidity of the air-conditioning chamber 18, the first space 22 is dehumidified by the dehumidifier 17 to have the air-conditioning-chamber target humidity, which will be described in detail later. The dehumidified air is blown to the second space 23 via the space connection opening 25.
The first space temperature sensor 28 is a sensor that takes the temperature of the air of the first space 22 and sends it to the system controller 10. As described above, since the outside air and the air sent from each living room 2 are mixed, it is desirable that the first space 22 is provided with the first space temperature sensor 28 downstream, that is, in the vicinity of the space connecting opening 25, so as to obtain information as the whole of the first space 22.
The first space humidity sensor 29 is a sensor that acquires the humidity of the air of the first space 22, i.e., the humidity of the first space 22, and transmits it to the system controller 10. For the same reason as the first space temperature sensor 28, it is also desirable to provide a first space humidity sensor 29 downstream, i.e., in the vicinity of the space connecting opening 25, so as to obtain information as the entire first space 22.
The second space 23 is provided with a space connecting opening 25 to the first space 22 at the upstream and a space connecting opening 25 to the third space 24 at the downstream. In addition, the second space 23 is provided with an air conditioner 9. With this configuration, the air dehumidified in the first space 22 is cooled or heated in the second space 23 by the air conditioner 9 so that the temperature of the air in the second space 23 becomes the set air-conditioning room target temperature. Then, the cooled or heated air is blown to the third space 24 via the space connection opening 25 with the third space 24.
The third space 24 is provided with a space connecting opening 25 to the second space 23 at the upstream and the conveyance fans 3a to 3d at the downstream. In addition, the third space 24 is provided with the humidifier 16. Further, the third space 24 is provided with an air-conditioning room temperature sensor 14 and an air-conditioning room humidity sensor 15 at the downstream, i.e., in the vicinity of the conveyance fans 3a to 3 d. With this configuration, the air cooled or heated in the second space 23 is humidified in the third space 24 by the humidifier 16 so that the humidity thereof becomes the air-conditioning room target humidity in the case of being lower than the air-conditioning room target humidity. The humidified air is then sent to the rooms 2a to 2d via the sending fans 3a to 3 d.
With this configuration, since the control of the target temperature of the air-conditioning room and the control of the target humidity of the air-conditioning room can be performed separately in separate spaces, efficient dehumidification and humidification can be performed. Next, a specific flow and effect of dehumidification and humidification will be described.
For example, in a high-temperature and high-humidity environment in summer or at the time of a rainy season, the air in the air conditioning room 18 is dehumidified or cooled. First, the air-conditioning-room humidity control unit 55 calculates a difference between the target humidity of the air-conditioning room and the humidity of the air-conditioning room 18, that is, the humidity of the third space 24. When the humidity of the third space 24 is higher than the target humidity of the air-conditioning room, the dehumidification is performed by the dehumidifier 17 provided in the first space 22. The air dehumidified in the first space 22 is blown to the second space 23. In the second space 23, when the temperature of the air in the second space 23 is higher than the set target temperature of the air-conditioned room, the air is cooled by the air conditioner 9 provided in the second space 23. Here, as for the humidity controlled in the first space 22, the relative humidity is changed by cooling in the second space 23. In contrast, in the present configuration, the air in the first space 22 is controlled by the air-conditioning-chamber humidity control unit 55 to be equal to or lower than a predetermined dehumidification humidity lower than the humidity (in this case, the relative humidity) of the conveyance air blown out of the air-conditioning chamber 18 by the conveyance fan 3. That is, the first space humidity calculating unit 58 estimates the cooling by the air conditioner 9, and calculates (reverses) the humidity to be reached by the first space 22.
Specifically, the first space humidity calculating portion 58 calculates the humidity (in this case, the relative humidity) to be reached by the air of the first space 22 by the following procedure based on the set target humidity (in this case, the relative humidity) of the transportation air, the set target temperature of the transportation air, and the temperature of the first space 22.
First, the absolute humidity, which is the moisture content of the carrier air, is calculated from the conditions of the set target humidity (in this case, relative humidity) of the carrier air and the set target temperature of the carrier air. In summer or rainy weather, after the second space 23 is cooled as described above, air is sent from the third space 24 to the rooms 2a to 2 d. That is, by determining the absolute humidity in the first space 22, the air sent to each of the rooms 2a to 2d becomes the target absolute humidity. The first space humidity calculating portion 58 calculates the absolute humidity of the transport air, and thereafter, detects the temperature of the first space 22. Thereby, the humidity at the temperature of the first space 22 to be reached (in this case, the relative humidity) can be calculated. In summer or rainy weather, the temperature of the second space 23 is cooled by the air conditioner 9 as needed with respect to the temperature of the first space 22. Therefore, the humidity (in this case, the relative humidity) of the air of the first space 22 is smaller than the humidity (in this case, the relative humidity) of the air of the second space 23. Therefore, the humidity (in this case, the relative humidity) of the air of the first space 22 is controlled to be a dehumidification humidity lower than the humidity (in this case, the relative humidity) of the conveyance air.
As described above, in summer or rainy weather, the air of high temperature and high humidity is blown to the first space 22. In the case of air, the higher the temperature, the more saturated water vapor amount, and the more water amount can be contained. If dehumidification is performed in this case, much moisture can be removed from the air only by slightly lowering the temperature of the air in the heat exchanger provided in the dehumidifier 17. That is, the air can be efficiently dehumidified.
In addition, when the air conditioner 9 and the dehumidifier 17 are installed in the same space of the air-conditioning room 18 during a rainy season, the temperature difference between the air outside the air conditioner 9 and the air-conditioning room 18 is small, and the air-conditioning room is in a thermally closed state. In this case, only the dehumidifier 17 operates, and the air is radiated by the dehumidifier 17, so that the temperature of the air-conditioning room 18 becomes higher than the outdoor temperature, and the air is sent to the rooms 2a to 2 d. However, the air heated by the heat radiation of the dehumidifier 17 is sent to the air conditioner 9 by performing dehumidification in the first space 22, and the air conditioner 9 performs a cooling operation and can be adjusted to a set target air-conditioning-room temperature. The air-conditioning room 18 is expected to be a relatively small space. Therefore, when the air conditioner 9 and the dehumidifier 17 are installed in the same space of the air-conditioning chamber 18, the air is cooled by the air conditioner 9 and heated by the heat radiated from the dehumidifier 17 at the same time, and thus it is difficult to control the temperature to the set target temperature. However, since the air-conditioning chamber 18 is partitioned, the heat radiation of the dehumidifier 17 can be separated from the second space 23 in which the air-conditioner 9 is present, and thus the control to the set target air-conditioning chamber temperature and the set target air-conditioning chamber humidity is facilitated.
In addition, for example, in the case of a low-temperature and low-humidity environment in winter, the air of the air conditioning room 18 is heated and humidified. First, the air-conditioning-room humidity control unit 55 detects the humidity of the air in the first space 22 to determine whether the air is to be dehumidified, but the air in winter, which is already at a sufficiently low humidity, is not to be dehumidified. That is, in the first space 22, only the indoor air from the first air supply opening 26 and the outdoor air from the second air supply opening 27 are mixed.
Next, when the air in the second space 23 is lower than the set target temperature of the air-conditioning room, the air is heated to the target temperature of the air-conditioning room set by the air conditioner 9. In this case, the humidity (in this case, the relative humidity) of the air in the second space 23 is greatly reduced by the heating. The air heated in the second space 23 is delivered to the third space 24 in a state where the condition of the target temperature of the air-conditioned room is satisfied.
In the third space 24, the air-conditioning-room humidity control unit 55 calculates a difference between the set air-conditioning-room target humidity and the humidity of the third space 24. When the humidity of the third space 24 is lower than the air-conditioning room target humidity, the air-conditioning room humidity control unit 55 humidifies the air by the humidifier 16 provided in the third space 24. Thus, the air sent from the sending fans 3a to 3d in the third space 24 has the set air-conditioning room target temperature and air-conditioning room target humidity.
In this configuration, the air heated by the air conditioner 9 is blown to the third space 24. Further, as for the air, the higher the temperature is, the more the moisture content can be contained, that is, the absolute humidity can be set to be larger. This allows the air in the third space 24 to efficiently absorb moisture from the humidifier 16. That is, the air in the third space 24 can be humidified to the set target humidity in the air-conditioning room more efficiently and delivered to each living room 2 by the delivery fans 3a to 3 d.
The air conditioning system of the present invention has been described above with the structure in which the space of the air conditioning chamber 18 is divided into three sections, but the above embodiment is merely an example and is not limited thereto.
For example, as shown in fig. 10, the second space 23 may be a space which doubles as the third space 24, i.e., the second-third space 30. In other words, the space for cooling or heating the air and the space for humidifying the air may be the same space.
In the case of a high-temperature and high-humidity environment in summer or at the time of rainy weather, the air is dehumidified in the first space 22 and cooled in the second-third spaces 30, as in the case of the three-division case. In addition, in the case of a low-temperature and low-humidity environment in winter, heating and humidification are simultaneously performed in the second-third spaces 30. In the present configuration, air having a lower temperature than the air-conditioning room is blown from the first space 22 to the second-third spaces 30, and the efficiency of humidifying air is inferior to the case of dividing into three sections. However, by providing the second to third spaces 30, the volume of the humidification space can be set larger than the third space 24. That is, the amount of air having a high humidity after humidification is larger in the second-third space 30 than in the third space 24, and thus the air can be humidified to the set target humidity in the air-conditioning room more efficiently. Moreover, the number of partitions 21 can be reduced from two to one, and the cost of the air-conditioning room 18 can be reduced.
In the above embodiment, a living room is shown, but the living room does not necessarily have to have a person, and can be regarded as a single space. That is, a corridor or a kitchen can be regarded as a single space, corresponding to a single living room, as long as the corridor or the kitchen is also partitioned to some extent.
In addition, the air conditioning system of the present invention can be applied to a single residence or a complex residence such as an apartment. However, in the case of applying the air conditioning system to a complex residence, one system corresponds to one house, and one house is not set as one living room.
